摘要:
A method of producing a contact structure for establishing electrical connection with contact targets. The contact structure is formed of a contact substrate and a plurality of contactors. The contactor is uniformly formed of conductive material and has an intermediate portion which is inserted in the through hole provided on the contact substrate in a vertical direction, a contact portion which is connected to the intermediate portion and positioned at one end of the contactor to function as a contact point for electrical connection with a contact target, and a base portion which is provided at other end of the contactor, and a spring portion which is substantially straight and upwardly inclined relative to the surface of the contact substrate and provided between the base portion and the intermediate portion.

A contact structure having a contact substrate and a plurality of contactors is a block of a large contact structure or a contactor assembly for establishing electrical connection with contact targets. The contact structure is formed of a contact substrate and a plurality of contactors in which each of the contactors has a curved portion for exerting a spring force in a vertical direction. The contact substrate has engagement mechanism at outer edges thereof so as to connect other contact substrates at any desired edges to establish the contactor assembly with desired size, shape and number of contactors.

Disclosed is a system and method for registering images from two medical imaging modalities in a six-degree-of-freedom coordinate space, for the purpose of providing real time registered imagery for optimization of medical procedures. The system and method uses fiducial that is visible to the first imager and in a fixed position and orientation relative to the second imager. The first imager may be an X-ray device such as a C-arm fluoroscope, and the second imager may be a Transrectal Ultrasound (TRUS) device.
摘要:
A method to automatically detect and rectify a tray block in a disk drive comprising detecting an occurrence of a tray block in a disk drive upon receiving a tray-out command or a tray-in command by determining whether the tray is in an intermediate position for a predetermined time period, the intermediate position being a position between a first position within a casing of the disk drive and a second position projecting completely outwards from the casing, the tray arranged to receive a record carrier when in the second position and being supported for movement between the first position and the second position. The detected tray block is rectified by cleaning a brush-commutator interface of a tray motor arranged to move the tray between the first position and the second position and is useful for optical recorders and/or players which have a design of a tray open/close mechanism.

A method for performing condition monitoring on a plurality of wind turbines arranged in a wind farm is disclosed. The method comprises the steps of: for each wind turbine, obtaining at least one vibration signal, each vibration signal representing vibrations of one or more monitored components of the wind turbine, e.g. moving gear parts or bearings; generating a plurality of faulty frequency indexes, each faulty frequency index corresponding to a monitored component, each faulty frequency index being generated on the basis of one or more of the obtained vibration signals, and each faulty frequency index being generated in such a manner that variations in the vibration signals introduced by variations in rotational speed of one or more rotating shafts of the wind turbine are filtered out; comparing faulty frequency indexes originating from different wind turbines of the wind farm; and based on the comparing step, evaluating the condition of each of the monitored components of the plurality of wind turbines. The method allows vibration levels of components to be easily compared on wind farm level, and faulty or failing components are easily and reliably detected.
摘要:
Methods and systems for controlling operation of a wind turbine. The method may comprise determining an alarm level for at least one component of the wind turbine. In the case that an alarm level for at least one component exceeds a predefined level, the method comprises estimating an expected remaining lifetime for the component under the current operating conditions, and controlling operation of the wind turbine in order to adjust the expected remaining lifetime for the component to a desired expected remaining lifetime for said component. Thereby, the expected remaining lifetime for the component can be prolonged until the next scheduled service event. Downtime of the wind turbine is considerably reduced, and unscheduled service events are avoided to the greatest possible extent. Mean time between inspections (MTBI) is also extended.

A method and system for removing periodic disturbances pertaining to turntable and spindle motor errors during recording of a blank optical information carrier. The periodic disturbances are determined in advance and removed only during recording by a repetitive control/learning feedforward control circuit (88).

A method and a system for controlling operation of a wind turbine are provided. The method includes determining at least one failure mode relating to one or more components of the wind turbine, estimating a remaining lifetime of the component under current operating conditions, determining one or more control schemes to control the operation of the wind turbine in order to adjust the remaining lifetime of the component to a desired remaining lifetime of the component, determining a power production yield for the determined one or more control schemes and selecting a determined control scheme for controlling the operation of the wind turbine that maximizes the power production yield.
